In November 2015, detectives in Liverpool contacted investigators from the Kent and Essex Serious Crime Directorate to tell them Tuan had been arrested and charged following the discovery of the cannabis operation in Bridport Street.

Kent detectives then charged him with the second offence.

Senior investigating officer Detective Sergeant Richard Spicer said: “Pham Tuan was a key player in a major drug supply operation, and stripping down a cannabis factory of that size would have undoubtedly made a big impact on the county’s drug network.

“Tuan may have felt like he had got away with it but his arrest should serve as a warning to others that no unsolved case is ever truly closed, and that if you break the law your crimes will catch up with you in the end.

“We have a zero tolerance approach to drugs and I am pleased Tuan will never again be able to grow cannabis plants within the UK.”
